[0001] The invention relates to the technical field of sludge treatment, in particular to an ultra-high pressure double-diaphragm low-temperature sludge dehydration and drying integrated equipment. Background Art

[0002] Sludge drying, also known as sludge dehydration, refers to the process of removing most of the water content from sludge through filtration or evaporation, generally referring to the use of self-evaporation facilities such as sludge drying plants.
